ID this WWII aircraft oxygen setup

[Dirk Pitt Fanatic]

Found this working setup a while ago in a house my parents bought. The owner had long passed away. Could anyone tell me what plane it may have come off of. I've spent hours trying to find it. Has inspection tags from Corpus Christi Texas Naval Base from the 50's and was stamped 1942 on the bottle.

Looks like a portable or "bolt on" rig for use in an aircraft that didn't have a built-in system. Corpus was a Training Command base, so SNJ? SNB? T-28? Early jet conversion trainer, the TV2 (a Navy T-33), had a built-in system, so I doubt it's one of those.
Cheers,
Wes

It could be from a number of different aircraft, to me it looks like a crew or passenger set up.

Is there a readable part number on the mounting plate or tags?
Everything else is standard parts
